According to the pallet discriminator mounted by the discriminator mounting method of the present invention, the second plate-shaped portion extends in a predetermined direction from one main surface of the first plate-shaped portion, and the predetermined direction A wireless identification tag is arranged along the line. Therefore, if one main surface of the first plate-like portion is arranged along the wall surface of the pallet with a hole, the second plate-like portion and the wireless identification tag are inserted into the hole. The plate-like portion and the wireless identification tag can be arranged inside the pallet. In addition, since the protrusion is formed so as to surround the joint portion between the one main surface and the second plate-like portion, the size of the hole to be inserted is larger than the size of the second plate-like portion and the wireless identification tag. If it is formed so as to be smaller than the outer periphery of the protruding portion, the hole can be surrounded by the protruding portion, so that water can be prevented from entering the pallet.
According to the discriminator mounting method of the present invention, the first plate can be removed so that the joint portion between the first plate portion and the second plate portion of the pallet discriminator attached to the pallet can be removed. Since the hole is formed in the shape portion, the second plate shape portion and the wireless identification tag can be removed. Further, since the first plate-like portion after the hole is drilled is removed, the first plate-like portion can be easily removed from the pallet. Furthermore, one main surface of the first plate-like part of the new pallet discriminator is arranged along the hole made in the pallet, and the second plate-like part and the wireless identification tag are inserted into the hole. Therefore, the second plate-like portion and the wireless identification tag can be arranged inside the pallet. Since the projection is brought into contact with the peripheral portion of the hole and welded, the projection is welded to the pallet so as to surround the hole, thereby preventing water from entering the pallet.

  Further, in the present invention, the projecting portion has a first projecting portion formed in an annular shape so as to arrange the joining portion in the closed region, and an annular shape so as to arrange the first projecting portion in the closed region. It is also preferable that the second projection portion is formed. Since the protrusion is composed of the first protrusion and the second protrusion formed so as to surround it, the adhesion to the pallet can be improved and water can enter the pallet more effectively. Can be prevented.

  According to the present invention, the second plate-like portion extends in a predetermined direction from one main surface of the first plate-like portion, and the wireless identification tag is arranged along the predetermined direction. Therefore, if one main surface of the first plate-like portion is arranged along the wall surface of the pallet with a hole, the second plate-like portion and the wireless identification tag are inserted into the hole. The plate-like portion and the wireless identification tag can be arranged inside the pallet. In addition, since the protrusion is formed so as to surround the joint portion between the one main surface and the second plate-like portion, the size of the hole to be inserted is larger than the size of the second plate-like portion and the wireless identification tag. If it is formed so as to be smaller than the outer periphery of the protruding portion, the hole can be surrounded by the protruding portion, so that water can be prevented from entering the pallet. Therefore, it was possible to provide a pallet discriminator and a discriminator mounting method capable of avoiding water intrusion into the pallet as much as possible.

  A state in which the pallet discriminator 10 according to the embodiment of the present invention is mounted on the pallet will be described with reference to FIG. FIG. 2 is a diagram illustrating a state in which the pallet classifier 10 is mounted on the pallet 20. The pallet 20 is a rectangular parallelepiped object and is made of synthetic resin. The surface having the largest area among the surfaces constituting the pallet 20 is used as the loading surface 203, and the surface facing the loading surface 203 is the back surface.

  The side surface of the pallet 20 includes a fork insertion port surface 201 and a girder surface 202. There are two fork insertion port surfaces 201, and the fork insertion port surfaces 201 are arranged to face each other. The fork insertion port surface 201 has two fork pockets 204. A fork of a forklift or a handlift is inserted into the fork pocket 204. When transporting the pallet 20, the fork inserted into the fork pocket 204 is lifted to hold and transport the pallet 20. Each fork pocket 204 penetrates from one fork insertion port surface 201 to the opposite fork insertion port surface 201. There are also two girder surfaces 202 arranged adjacent to the fork insertion port surface 201. This girder surface 202 is not provided with an opening such as a fork pocket.

  As shown in FIG. 2, the pallet classifier 10 has holes formed in the stacking surface 203 and the girder surface 202 of the pallet 20 and is arranged in accordance with the holes. In addition, the pallet identifier 10 may be disposed so as to fit a hole between the fork pockets 204 of the fork insertion port surface 201 of the pallet 20.

  Subsequently, a method of mounting the pallet discriminator 10 on the pallet 20 will be described with reference to FIGS. 3 (a) to 3 (c). FIGS. 3A to 3C are diagrams for explaining a procedure for mounting the pallet discriminator 10 on the pallet 20. First, as shown in FIG. 3A, a pallet discriminator 10 and a pallet 20 are prepared. Next, a hole 202a is made in the girder surface 202 which is a surface on which the pallet discriminator 10 is to be mounted. The diameter of the hole 202a is set such that the second plate-like portion 13 and the wireless identification tag 14 of the pallet discriminator 10 can be inserted, and the first plate-like portion of the pallet discriminator 10 is further set. 11 is set so as to be smaller than the diameter of the protrusion 12 formed on the substrate 11.

  Next, as shown in FIG. 3B, the pallet discriminator 10 is inserted into the hole 202a formed in the beam surface 202 of the pallet 20. The second plate-like portion 13 and the wireless identification tag 14 of the pallet discriminator 10 are arranged inside the pallet 20. In this state, the identification attachment 10 for pallets is pressurized in the direction of arrow A in FIG. 3B by the welding horn 30 of the ultrasonic welding apparatus. Although the entire ultrasonic welding apparatus is not illustrated, the ultrasonic welding apparatus used here includes a positioning cylinder, an ultrasonic actuator, an ultrasonic oscillator, and a welding horn 30.

  The ultrasonic welding apparatus holds the pallet 20 with a positioning cylinder and adjusts the positional relationship with the welding horn 30. The ultrasonic vibration generated by the ultrasonic oscillator is transmitted to the welding horn via the ultrasonic actuator. As the ultrasonic oscillator, an electrostrictive vibrator or a magnetostrictive vibrator is used. The ultrasonic actuator includes a booster, and the ultrasonic vibration transmitted from the ultrasonic oscillator is transmitted to the welding horn 30 with the vibration amplitude being increased by the booster.

  The ultrasonic actuator and the welding horn 30 are fastened along a predetermined axis along the direction of arrow A in FIG. The welding horn 30 is configured to move in the left-right direction in FIG. 3B along this predetermined axis. Accordingly, the welding horn 30 moves to the position of the first plate-like portion 11 of the pallet discriminator 10 in FIG. 3B and holds the pallet discriminator 10 while pressurizing it with the pallet 20. The pallet discriminator 10 is welded to the pallet 20 by applying ultrasonic vibration. When the pallet discriminator 10 is welded to the pallet 20, the projections 12 formed on the first plate-like portion 11 of the pallet discriminator 10 are welded so as to be crushed. c).

  FIG. 4 shows a state in which a section of the pallet discriminator 10 is also drawn in FIG. As shown in FIG. 4, the second plate-like portion 13 is inserted into a hole 202 a provided in the girder surface 202 of the pallet 20. The 1st projection part 121 and the 2nd projection part 122 which are provided in the 1st plate-shaped part 11 are arranged and welded so that hole 202a may be surrounded. Therefore, the hole 202a is blocked by the first projecting portion 121 and the second projecting portion 122, and cleaning water or the like does not enter the inside of the pallet 20.

  The welding horn 30 used in the present embodiment is formed by cutting out from a rectangular parallelepiped raw material block (made of duralumin). A convex portion is provided on the surface of the welding horn 30 that contacts the first plate-like portion 11 of the pallet discriminator 10. The cross section of this convex part is arcuate.

  Subsequently, when the pallet discriminator 10 is mounted on the pallet 20, a method of replacing the pallet discriminator 10 with a new pallet discriminator 10 and mounting the pallet discriminator 10 will be described with reference to FIGS. ). FIG. 5A to FIG. 5C are diagrams for explaining a procedure for removing the pallet discriminator 10 already mounted from the pallet 20. As shown in FIG. 5A, a pallet 20 on which the pallet classifier 10 is mounted is prepared. Here, a welding horn 40 is prepared in order to remove the second plate-like portion 13 of the pallet discriminator 10. The welding horn 40 functions as a part of the ultrasonic welding apparatus in the same manner as the welding horn 30 described in FIG. 3B. In this case, the second plate-like portion 13 and the first plate are used. It is used for melting and removing the joint portion with the shape portion 11. The diameter of the welding horn 40 is set to be smaller than the diameter of the hole 202 a provided in the girder surface 202 of the pallet 20 and wider than the width of the second plate-like portion 13. The center line of the welding horn 40 and the center line of the hole 202a (or the center line of the first plate-like portion 11) are matched, and the welding horn 40 is moved in the direction of arrow B in FIG. . When the welding horn 40 comes into contact with the first plate-like portion 11 of the pallet discriminator 10, the welding horn 40 is ultrasonically vibrated and further moved in the direction of the arrow B, so that the first plate-like portion 11 has a hole 11a. And the second plate-like portion 13 is removed. This removed state is shown in FIG.

  FIG. 5 (b) also shows the first plate-like portion 11 in cross section in order to show a state in which the hole 11 a is opened in the first plate-like portion 11 of the pallet discriminator 10. Thus, when the hole 11a is made in the first plate-like portion 11 and the second plate-like portion 13 is removed, the first plate-like portion 11 is moved in the direction along the spar surface 202 of the pallet 20. In addition, the second plate-like portion 13 does not become an obstacle. Therefore, when a force is applied to the first plate-like portion 11 in the direction along the girder surface 202, the first protruding portion 121 and the second protruding portion 122 peel from the pallet 20, and the first plate-like portion 11 can also be removed from the pallet 20.

  A state in which the pallet discriminator 10 is removed from the pallet 20 is shown in FIG. When the pallet discriminator 10 mounted in this way is removed from the pallet 20, a state similar to the state of the pallet 20 shown in FIG. Therefore, a new pallet discriminator 10 can be mounted on the pallet 20 by preparing a new pallet discriminator 10 and taking the same method as described with reference to FIGS. 3 (a) to 3 (c).

  According to this embodiment, in the pallet discriminator 10, the second plate-like portion 13 extends in a predetermined direction from the one main surface 111 of the first plate-like portion 11, and along the predetermined direction. A wireless identification tag 14 is arranged. Therefore, when the one principal surface 111 of the first plate-like part 11 is arranged along the beam face 202 of the pallet 20 with the hole 202a, the second plate-like part 13 and the wireless identification tag 14 are placed in the hole 202a. Thus, the second plate-like portion 13 and the wireless identification tag 14 can be arranged inside the pallet 20. Moreover, since the projection part 12 is formed so that the junction part of the 1st plate-shaped part 11 of the 1st plate-shaped part 11 of the pallet discriminator 10 and the 2nd plate-shaped part 13 may be enclosed, the hole 202a to insert is formed. Since the projection 202 can surround the hole 202a if the size is larger than that of the second plate-like portion 13 and the wireless identification tag 14 and smaller than the outer periphery of the projection 12, the pallet Intrusion of water into the interior of the 20 can be prevented.

  Moreover, since the projection part 12 is comprised by the 1st projection part 121 and the 2nd projection part 122 formed so that it may be enclosed, the adhesiveness with respect to the pallet 20 can be improved, and the inside of the pallet 20 can be improved. Water penetration can be prevented more effectively.
